node.js - Mongoose - get array-entry of subdocument -


i've document looks this:

{     "_id" : objectid("5979f7a3bdbfcb25e6c32b95"),     "name" : "company 1",     "address" : {         "street" : "mainstreet 4",         "plz" : 1010,         "ort" : "vienna",         "land" : "at"     },     "status" : "active",     "settings" : [          {             "key" : "sett1",             "value" : "val1"         }     ],     "users" : [          {             "firstname" : "mike",             "lastname" : "bold",             "username" : "miky123",             "password" : "mypassword",             "token" : "ab78ab99684ef664654a65468b86de64",             "status" : "active",             "role" : "admin",             "settings" : [                  {                     "key" : "e1",                     "value" : "w1"                 },                  {                     "key" : "e2",                     "value" : "w2"                 }             ]         }     ] }

i want retrieve password-value can verify it. tried following code value:

company.findone({"users.username": req.body.username}, {"users.username.$": 1},function(err, user){   res.json(user);     });

by using projection operator $ subset of document:

{   "_id": "5979f7a3bdbfcb25e6c32b95",   "users" : [      {       "firstname" : "mike",       "lastname" : "bold",       "username" : "miky123",       "password" : "mypassword",       "token" : "ab78ab99684ef664654a65468b86de64",       "status" : "active",       "role" : "admin",       "settings" : [          {           "key" : "e1",           "value" : "w1"         },          {           "key" : "e2",           "value" : "w2"         }       ]     }   ] }

so i've tried password by:

console.log(user.users[0].password);

but there error-message:

typeerror: cannot read property '0' of undefined

do have idea how retrieve password-value?

thanks!
